The RCA Spectra 70 was a line of electronic data processing (EDP) equipment manufactured by the Radio Corporation of America’s computer division beginning in April 1965. The Spectra 70 line included several CPU models, various configurations of core memory, mass-storage devices, terminal equipment, and a variety of specialized interface equipment. Competition in the mainframe market was fierce, and in 1971 the company sold the computer division and the Spectra 70 line to Sperry Rand, taking a huge write down in the process.

has abstract	The RCA Spectra 70 was a line of electronic data processing (EDP) equipment manufactured by the Radio Corporation of America’s computer division beginning in April 1965. The Spectra 70 line included several CPU models, various configurations of core memory, mass-storage devices, terminal equipment, and a variety of specialized interface equipment. The system architecture and instruction-set were largely compatible with the non-privileged instruction-set of the IBM System/360, including use of the EBCDIC character set. While this degree of compatibility made some interchange of programs and data possible, differences in the operating system software precluded transparent movement of programs between the two systems. Competition in the mainframe market was fierce, and in 1971 the company sold the computer division and the Spectra 70 line to Sperry Rand, taking a huge write down in the process. (en)
